Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A composition comprising a polycarbonate-polydiorganosiloxane block copolymer reinforced with an effective reinforcing amount of a polymeric aromatic amide in a physical form which achieves reinforcement. 
     
     
       2. The composition in accordance with claim 1 wherein the polymeric aromatic amide is in the form of a fiber, mat or whisker. 
     
     
       3. The composition in accordance with claim 1 wherein the polymeric aromatic amide is from about 0.5 to about 85 weight percent of the block copolymer and the polymeric aromatic amide. 
     
     
       4. The composition of claim 1 in the form of a sheet. 
     
     
       5. The composition of claim 1 compression molded into an article.
